Diagnosis The sprain is easy to diagnose just by looking at it. It is a patient who has sprained a joint, most commonly the wrists and ankles, and has swelling and pain. Try to gently move the joint so that you can appreciate the degree of resistance it presents. A very loose joint, which makes movements that are not proper for it, is an unstable joint and should be immobilized. 216
